Thread specification M6~M48:

The anchor bolt generally uses Q235 steel, which is light and round. Rebar steel (Q345) strength is large, do the nut wire buckle is not easy to light round. For the light round anchor bolt, the buried depth is generally 25 times its diameter, and then make a 90-degree bending hook of about 120mm long. If the bolt diameter is very large (such as 45mm) buried depth is too deep, you can weld the square plate at the end of the bolt, that is, to make a large head (but there are certain requirements). The buried depth and bending hook are to ensure the friction between the bolt and the foundation, not to make the bolt pull out and damage.



The anchor bolts can be divided into fixed anchor bolts, movable anchor bolts, swollen anchor bolts and bonded anchor bolts. According to the different appearance, it is divided into: L-type embedded bolts, 9-character type embedded bolts, U-type embedded bolts, welding embedded bolts, bottom plate embedded bolts.


1. The Fixed anchor bolt, also known as the short anchor bolt, is poured together with the foundation and is used to fix the equipment without strong vibration and impact.
2. The Active anchor bolt, also known as the long anchor bolt, is a detachable anchor bolt, used to fix the heavy mechanical equipment with strong vibration and impact.
3. The expansion anchor bolts are often used to fix the simple static equipment or auxiliary equipment. The installation of the anchor bolts shall meet the following requirements: the diameter of the anchor bolt from the bolt center to the foundation edge; the anchor bolts shall not be less than 10MPa; the drilling holes shall prevent the reinforcement and buried pipe in the foundation; the drilling diameter and depth shall match the anchor bolts.
4. Bonded anchor bolt is a kind of anchor bolt commonly used in recent years, whose method and requirements swell the anchor bolt together. But when bonding, pay attention to the hole debris blow clean, and shall not be damp.
